Windows Vista Business 32-Bit is pre-installed by default,HP 454931-001which is quite alright with a total capacity of 3 GB RAM. If one should choose to upgrade to more than 4 GB RAM, a 64-Bit operating system is definitely a better choice, since 32-Bit systems can only address up to 4 GB of RAM. The integrated graphics adapter and the operating system already use up quite a large part of those 4 GB, meaning that only a bit more than 3 GB actually remain for the user.HP 455804-001
Additionally, one can downgrade to Windows XP, drivers and tools for that are fortunately available on HP's website.Depending on the country, the 2230s is also partly available with pre-installed FreeDos, at a lower price. One could still install Windows XP or Windows Vista Business later, if one already had a license.HP 460143-001
We were especially excited about SUSE Linux Desktop 10, which should be compatible to this device, as stated by the manufacturer. The installation is carried out via an image for SUSE Linux Desktop 10 SP2, SLED-10-SP2-x86_64-DVD1.iso, downloaded from Novell's homepage. Access to updates is available for 60 days through a requestable activation code (free of charge), a version including a year-long access to updates is available for about 47 Euros. HP 462337-001
No problems came up during the installation at first, but the auto-detect routines do not seem to be too comprehensive, the network devices were not discovered and the included Marvell Yukon card does not appear on the list for manual selection either. Not surprisingly, internet access via wired or wireless LAN was not available right after the installation, we did not try any further due to lack of time.HP EV088AA
In any way, the support for included components is frustrating considering the fact that the operating system is listed as compatible, it is thus not recommendable for Linux beginners. Further attempts with a Linux Life CD (Knoppix 6.0) showed that no WLAN-access is possible without further interventions. In contrast, internet-access over the wired adapter did work immediately.HP EV089AA
All in all the keyboard offers a good feel, featuring a standard layout. The normal keys are about 18mm wide and about 17mm deep, which is sufficient for a mini-notebook. However, this was reached at the expense of other important keys which became smaller in turn, for instance the really smal shift-keys. Additionally, the up-key was placed just to the right of the right shift key, making mistakes while typing probable in the beginning. HP EX940AA
At large, the keyboard's layout appears to be somewhat left-leaning, due to the very small keys at the left edge (especially "^", tab, Caps Lock key, left shift-key, left ctrl-key). Therefore, the right hand will partly be placed on the touch pad when touch typing, due to the relative position of touch pad and keyboard. Fortunately, the touch pad is not too sensitive in terms of "tap-to-click".HP EX941AA
Stroke, feedback and compressive strength of the single keys are without any distinctive feature. HP HSTNN-C17CThe keyboard can become quite noisy when typing aggressively, especially the space bar.Additional keys are featured through touch sensitive areas on a bar above the keyboard. These are used for launching the HP Info Center (Presentation Settings), which is used for starting any user-defined application. It also allows for controlling the wireless module, as well as muting and volume.HP HSTNN-DB31
The touchpad, measuring 72mm in width and 53mm in depth, is quite comfortable for a 12"-device. Its surface's gliding properties are not optimal, but still good. Mechanically seen, it is very precise, the pointer can be brought to any position with ease. Fortunately, there's also a vertical, optically marked area for scrolling, but it is not possible to simply switch off the touch pad via a key or a combination with the fn-key.HP HSTNN-DB32
The touchpad's keys are toggle switches, their stroke, sound and sensitivity is alright once one gets used to press the side facing the user. HP HSTNN-IB31The keys are not really quiet, but not noisy either. There is a finger print reader as well, located on the bottom right corner, its location might not be optimal at times. Depending on one's individual habits, one might happen to accidentally hit the reader, with the palm of the hand, automatically causing the HP ProtectTools Security Manager to start. Moreover, the reader might be calibrated a bit too sensitive: we could not get it to read prints of the same finger, recognized as identical, while trying to register a finger print.HP HSTNN-IB32
As a notebook really suited for professional usage, the HP Compaq 2230s of course features a display with a matt surface. From an ergonomic point of view, it is good that the 12.1" LCD display (Typ:CMO 1232 (N121IA-L01) von Chi Mei Optoelectronics) barely reflects at all, making it suited for permanent professional usage at workstations as well. The WXGA-panel's native resolution is a common 1280x800 pixel. HP HSTNN-IB42
HP Compaq 2230s during outdoor usageThe 16:10 wide-screen LCD- display reached an average value of 187 cd/m² during the measurement of light density, the screen should be somewhat brighter for being able to comfortably work outside. HP HSTNN-LB31
The contrast (using the power supply) reached a value of about 184:1,HP HSTNN-LB42 with a minimal brightness (black value) of 1.12 cd/m² and maximum value of 206 cd/m² for brightness in the screen's center.The HP Compaq 2230s reached a good value of 83% for illumination. This means that the variance of light density (during mains operation) between the brightest (center) and the darkest segment of the display (bottom right corner) amounted to about 17% (170.3 cd/m²). A maximum brightness of only 186.1 cd/m² could be measured while using the battery.HP HSTNN-OB31
While subjectively looking at background pictures of a different brightness, HP HSTNN-OB42one can, depending on the angle of viewing, only find minor formation of shades on the HP Compaq 2230s' display.Measuring the reachable angles of viewing also brought a very good result horizontally, but the optimal angles for viewing and slanting are quite a bit lower vertically. The picture shown is, subjectively seen, sharp and legible, despite the high resolution.HP NBP6A48A1
Despite what the labels on the case and the information on HP's homepage says, HP 462889-121 the HP Compaq 2230s is based on the Centrino 2 platform and does allow for choosing an up-to-date Penryn CPU. The model we tested featured a Penryn Core 2 Duo P7370 CPU (manufactured in 45nm) at 2 GHz. Besides those Core 2 Duo Pxxx processors, which have a low power loss of 25 watt, one can also choose from Core 2 Duo Txxx CPUs, which have a somewhat higher Thermal Design Power (TDP) of 35 watt. HP 462889-421
Therefore, one cannot really criticize the overall performance of the tested HP Compaq 2230s (featuring two DDR2 modules, HP 462890-151 PC2-6400, and a total capacity of 3,096 MB) with Windows Vista Business installed. The system supports a maximum of 8 Gigabyte RAM with the compatible modules, as HP states. The notebook's performance is therefore sufficient for the usual work around the office and the use of such applications. The business-notebook reaches a fairly good performance value of 4181 points in PCMark 05. The integrated chipset graphics adapter (Intel GMA 4500 MHD) is also designed for this range of applications.HP 462890-161
An Intel GMA 4500MHD suffices as an integrated graphics solution for the HP Compaq 2230s,HP 462890-251 its performance is certainly enough for the usual office applications. It is also by far sufficient for presenting Windows Vista's Aero-Glass, but better solutions are available for gaming and displaying more complex 3D-applications. The HP Compaq 2230s reaches a score of only 1487 points in the benchmark 3DMark03, using the Intel driver version 7.15.10.1502. The CB-GFX-value of 510 the 4500MHD reached in a shading-test with Maxon's Cinebench R10 is also reltively low. HP 462890-541
Vista performance indexThere are also some options to choose from in terms of mass storage for the HP Compaq 2230s: Serial-ATA-hard disks with a capacity of 160, HP 462890-751250, or 320 Gigabyte are available, but only at 5400 rpm. Moreover, the HP 3D Drive Guard protects the hard disk from losing data through shocks, at least to a certain degree, since the hard disk is firmly connected to the notebook's frame on the one side. On the other side, a 3D-sensor notices sudden movement, causing the HP Drive guard software to park the hard disk's head in the worst possible case. HP 462890-761
The model we tested featured a 250GB, 5400 rpm Serial-ATA hard disk from Seagate (ST9250827AS), which achieved an average data transfer rate of 49,3 MB/s in HD Tune's hard disk test. A further mass storage device offered by the tested HP Compaq 2230s is an optical drive (TSSTcorp CDDVDW TS-L633L) by Toshiba Samsung Storage Technology Cooperation.HP 482186-003
The notebooks becomes fairly loud right after switching it on,HP 484170-001 but the system noise evens out to an average of 34.2 dB(A) while idling. Nevertheless, top values of up to 40.9 dB(A) were measured in idle mode.Under work load, this notebook does not become much more noisy with a maximum value of 42.1 dB(A), but this noise level is clearly audible. While the hard disk works fairly quietly at 33.1 dB(A), the optical drive works noisily at 49.5 dB(A) while transfering data, it works a bit more quiet while playing DVDs (38.4 dB(A)).HP 484170-002
